Pursuant to its defect investigations concerning the shattering of certain panoramic sunroofs, Korea proposes the establishment of an informal working group to prepare amendments to UN Regulation No. 43 and GTR No. 6 to specify test methods for evaluating panoramic sunroof glazing.

The main objective of this proposal is to develop an amendment to UN GTR No. 6 on Safety Glazing concerning clarification of the methods (e.g. 227g ball drop test), etc. for testing and evaluating the mechanical strength of toughened glass so that the safety of a panoramic sunroof is assured.

OICA and CLEPA comments on the Korean proposal to amend GTR No. 6 and UN Regulation No. 43 in response to issues identified in its defect investigation concerning panoramic sunroofs.

Correction to clarify that the scope of the GTR covers windscreens and panes for cars and trucks and to harmonize the text with ISO 3537/ UN R43. The present text could be read to limit the scope of windscreens and double window panes.

Presentation on Korean investigations that identify certain conditions under which ceramic printing (black enamel) weakens toughened glass such that the glass no longer meets the mechanical strength requirements of GTR 6, UN R43 or FMVSS 205. Korea proposes amending the UN glazing regulations.

Proposal to amend the methodology of the 227g ball drop test for toughened glass in order to assess its mechanical strength (resistance against outside impact). This proposal stems from Korean testing that demonstrated inadequate mechanical strength of toughened glass treated with ceramic printing.
